Height of a mountain is 5348.9 meter.

1 kilometer is equal to 1000 meter.

The meter, symbol m, is the primary unit of period in the international system of gadgets, although its prefixed paperwork also are used relatively regularly.

A meter is a general metric unit identical to about three feet 3 inches. This means that a meter is part of the metric gadget of dimension. Guitars, baseball bats, and backyard sticks are examples of items which might be approximately one meter lengthy. Meters also are used to measure distances in races, inclusive of strolling and swimming.

Meter readings tell power suppliers how a lot gasoline and energy you are the use of. In case you do not give your provider meter readings they may have to guess your usage. You typically turn out to be paying too much or too little while this occurs.

The concentration of ozone in a sample of air that has a partial pressure of O3 of 0.33 torr and a total pressure of air of 695

Goryan [66]

Answer:

0.047 %

Explanation:

Step 1: Given data

Partial pressure of ozone (pO₃): 0.33 torr

Total pressure of air (P): 695 torr

Step 2: Calculate the %v/v of ozone in the air

Air is a mixture of gases. We can find the %v/v of ozone (a component) in the air (mixture) using the following expression.

%v/v = 0.33 torr/695 torr × 100%

%v/v = 0.047 %

What will be the boiling point of a solution of 8 moles of sodium dichromate (Na2Cr2O7) dissolved in 8 kg of water? Use the foll

nexus9112 [7]

Answer:

1. 374.69 K

Explanation:

Hello,

In this case, pure water's boiling point is 373.15 K, thus by considering the boiling point increase equation:

$\Delta T=imKf$

Whereas i=2 since two ionic species are formed,actually, the experimental value is 2.42 so better work with it, thus:

$\Delta T=2.42*(\frac{8}{8}m)*0.512 Km^{-1}=1.239K$

Thus, the required boiling point is:

$T_b=373.15K+1.239K\\T_b=374.69K$

Regards.

Which reactants would lead to a spontaneous reaction?

balandron [24]

Answer: Option (b) is the correct answer.

Explanation:

The elements which have excess or deficiency of electrons will react readily.

Atomic number of Mn is 25 and electronic configuration of $Mn^{2+}$ is [Ar] $4s^{0}3d^{5}$ . This configuration is stable.

Atomic number of Cr is 24 and electronic configuration of $Cr$ is [Ar] $4s^{1}3d^{5}$ . This configuration is not stable.

Atomic number of Fe is 26 and electronic configuration of $Fe$ is [Ar] $4s^{2}3d^{6}$ . This configuration is stable.

Atomic number of Cu is 29 and electronic configuration of $Cu^{2+}$ is [Ar] $4s^{0}3d^{9}$ . This configuration is not stable.

Atomic number of Al is 13 and electronic configuration of Al is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{1}$ . This configuration is not stable.

Atomic number of Ba is 56 and electronic configuration of $Ba^{2+}$ is [Kr] $4d^{10}5s^{2}5p^{6}$ . This configuration is stable.

Atomic number of Mg is 12 and electronic configuration of $Mg^{2+}$ is $1s^{2}2s^{2}2p^{6}$ . This configuration is stable.

Atomic number of Sn is 50 and electronic configuration of Sn is [Kr] $4d^{10}5s^{2}5p^{2}$ . This configuration is stable.

Thus, we can conclude that out of the given options, only Fe and $Cu^{2+}$ reactants would lead to a spontaneous reaction as they have incomplete sub-shells. Therefore, in order to gain stability they will readily react.
